Best smoke/coffee shops in Amsterdam

I'm off to the Cannabis Cup tomorrow (along with Ajax v Real Madrid on Tues), and wanted to sample some of the coffee shops there. Haven't been since I was a kid, and want to avoid obvious tourists traps, unless they have spectacular gear.

I've heard great things about Nepalese Cream/Temple Ball stuff. Anywhere recommended to buy these, or even something more potent? I want to sample pretty much the most memorable stuff there is, so all recommendations would be greatly appreciated.

Barney's Lounge and The Dolphin were my favorite.

I like Hill Street Blues, if you can get the seats downstairs beside the canal its EXCELLENT! And the Bulldog cafe does beautiful Super Silver Haze and New York City Diesel. Get Blueberry if you can but its not a very "active" stone.

I like Route 66, theres sofas all over so you can just lie all over them and smoke a joint

I also liked Reggae Reggae, they do some nice weed especially the Northern Lights and the K2

Route 66 is where I saw some business guy, first time ever smoking, INHALE a blunt to the point where the budtender was like "I told you not to smoke like a cigarette, maybe you'd best enjoy that at home"...and off he went into the world, like a deer in the headlights! Id recommend their hot chocolate with a spliff, an excellent choice always!
